All the appropriate safety precautions must be taken when electrically operated equipment is used, in order to reduce the risk of fire outbreaks, electric shock and injuries to persons.
-Keep the work zone clean and orderly. Accidents are more likely to occur in untidy areas and environments.
-Before beginning work, make sure that the revolution monitor is in a perfect condition. Damaged or broken parts must be repaired or replaced by competent personnel authorized by the Manufacturer.
-All verifications, inspections, cleaning and maintenance operations, part changes and replacements must be carried out with the revolution monitor disconnected and the plug removed from the power socket.
-It is absolutely forbidden for children, unauthorized and/or inexpert persons to touch or use the digital revolution monitor.-Make sure that the electricity system complies with the laws in force. Make sure that the earthing is efficiently connected when the instrument is installed. Check to be sure that the power socket is suitable, that it complies -The revolution monitor must never be stopped by detaching the plug from the power socket. Moreover, never use the cable to pull the plug from the socket.
-Periodically check to be sure that
the cable is in a perfect condition and replace it if damage is discovered. This operation must only be carried out by competent and authorized persons. Only use extension cables of the permitted -Protect the cable against high temperatures, lubricants and sharp edges. Do not twist or knot the cable.-Do not allow children or unauthorized persons to touch the cable when the instrument is plugged in.
Before installation, inspect the outer structure of the revolution monitor. If the units If this check reveals anything irregular, the revolution monitor must be sent to CAMLOGIC Snc to be restored to efficiency. CAMLOGIC revolution monitor can be allowing the power cable to be fixed in the most favourable position ( Fig.1 ).
The unit can be mounted by a direct connection ( with M6 threading in the front machine to which the revolution monitor is connected. The type of connection can, however, be modified afterwards direct connection and this means that no modification is necessary. Connection to the spinning shaft is normally the revolutions can be installed so that the cable input is turned at 90° intervals,of one of these three options is determined by the structural characteristics of the since both the flanged type and bracket are fixed to the body of the revolution monitor by the threaded holes of the carried out through the coupling supplied by the Manufacturer. In any case, the coupling must be dimensionally part of the revolution monitor ), with flange connection or on a bracket. The choice type and marked.

The conductors forming the power supply and signal carriyng cable must have an adequate cross-section so that the current density, in each conductor, is no higher than 4 A/mm². One of these is used only for the earthing of the revolution monitor. The cross-section of the conductors must also be adequate in relation to the length of the cable used to avoid a drop in voltage along the cable over the values prescribed by the regulations on the subject. It is likewise reccomended to use flexible cables with an adequate outside diameter for the fair-leads used ( not supplied )to ensure a perfect seal of the cable clamp on the power supply and signal carriyng patible with the characteristics of the revolution monitor shaft and must allow a modest float to compensate for any misalignments in the installation.
The joint furnished by the Manufacturer is not fit to power transmissions, it must be used only in the context of supply.

Instructions Manual No. 01527 07.05 - Rev. 00
By the terminal box there is the wiring plate ( Fig.2 ) which has printed on it the
wiring diagram for the power supply and use of the revolution monitor.
CAUTION: There is a screw in the terminal board compartment which is used for
the earthing the revolution monitor. This screw must be connected to the yellow-green
conductor ( only green for the USA ) of the power cable.
The ground connection of the revolution monitor, through the yellow-green conductor,
Always check that the mains voltage and frequency correspond those given up on the plate of the revolution monitor before powering up.
For connections to the terminal board use fork cable terminals; for the ground connection use an eyelet cable terminal.
After having been powered, the revolution monitor starts by lighting the led and energizing the relay for ten seconds. This allows the controlled machine to reach operating rate and to keep the relay energized if the number of revolutions to check has been correctly entered. The relay switch contact is commutated ( led on ) for detected revolutions of the value entered ( Set-point ) on the selectors ( Fig.2 ) or higher. If the revolutions are less than the Set-point, the relay is released with contact commutation to the hold position and led off. The detected number of revolutions is updated every two seconds, corresponding to the maximum energizing delay time of the relay when the Set-point is reached.
The Set-point is set on the selectors ( Fig.2 ) in
different ways, depending on the version:
CAMLOGIC revolution monitors need no routine
maintenance. Possible extraordinary maintenance is
restricted to replacing parts that are deteriorated
by use. The unit must not be lubricated; the
shaft, the only moving part, is mounted on ball
bearings with permanent lubrication.
